NUT-LOCK.

Specification of Letters Patent.

Patented Jan. 5, 1909.

Application filed January 28, 1908. Serial No. 413,052.

To all whom it may concern:

Be it known that 1, ROBERT L. a citizen of the United States, residingat Springfield, in the county of Greene and State of Missouri, haveinvented certain new and useful Improvements in Nut-Locks, of which thefollowing is a specification, reference being had to the accompanyingdrawings.

My invention relates to improvements in nut-locks for the bolts ofrail-joints and other structures.

The object of the invention is to provide a simple and practicalnut-locking device which will be inexpensive in construction, easy toapply and remove and very effective for the purpose intended.

With the above and other objects in view, the invention consists of thenovel features of construction and the combination and a1- rangement ofparts hereinafter described and claimed, and illustrated in theaccompanying drawings, in which F i ure l is a side elevation of arail-joint showing the application of my invention thereto; Figs. 2 and3 are respectively, horizontal and vertical sections taken on the planesindicated by the lines 22 and 33 MANGAN,

in Fig. 1; Fig. 4 is a perspective view of the washer or fish-plate; andFig. 5 18 a similar view of the locking plate.

In the drawings I have illustrated my invention embodied in an improvedrail-joint which consists of the meeting ends of two track rails 1, 2,two fish-plates 3, 4 and a plurality of transverse bolts 5. The rails l,2 are of the usual form and have in their webs openings or slots toreceive the bolts 5 and which aline with similar openings in thefish-plates or washer-plates 3, 4. The open ings in the fish-plate 3have squared outer portions to receive squared portions formed upon thebolts adjacent to the heads of the latter. Each of the latter has avertical portion 6 which is apertured and adapted to fit against thewebs of the track rails, and a horizontal or angular lower portion 7adapted to rest upon the base flanges of said rails. The outer edges ofthe lower or base portions 7 of the fish-plates project beyond the edgesof the base flanges of the rails and are notched as at 8 to receivespikes which fasten the rails upon the cross ties.

The washer or fish-plate 4 which is preferably upon the outer side ofthe track rails is formed at one end of its vertical or upright whichformed cent to the opposite end of the plate 4 is a horizontallydisposed projection or lug 11 which projects outwardly from the verticalportion 6 of said plate at a point adjacent to its end and which isformed adjacent to its outer end with a vertical aperture 12. Said lug11 is preferably made independent of the fish-plate 4 and is securedtherein by reducing its inner end to provide a stop shoulder, passingthe reduced end through an opening in the fish-plate so that theshoulder engages the outer face of the latter, and then upsetting theinner extremity of the lug in a flared or enlarged portion of theopening in the fish-plate, as clearly shown in Fig. 2.

The nuts 13 of the bolts 5 are screwed up against the outer face of thewasher or fishplate 4 and are adapted to be locked against rotation by alocking member or plate 14 formed with a plurality of openings 15adapted to receive said nuts. The locking plate 14 is removably securedupon the plate 4 by forming at one of its ends an outwardly curved orbent tongue 16 which is adapted to be inserted in the opening 10 in theextension or lug 9; and by forming adjacent to the other end of thelocking plate 14 a slot or opening 17 which receives the horizontally orlaterally projecting lug 11. The opening 17 is formed a short distancefrom the end of the locking plate 14 and the latter is made slightlylonger than the washer or fish-plate 4 so that said end of the lockingplate projects beyond the adjacent end of the plate 4 in order that thelocking plate may be readily removedfrom the nuts by insorting aninstrument under said projecting end of the locking plate. The lockingplate is retained in position upon the nuts by the engagement of thetongue 16 with the extension or lug 9 and by inserting a split pin orkey 18 in the vertical aperture 12 in the lug 11.

From the foregoing it will be seen that my improved nut-lock isespecially well adapted for locking the nuts on a series of bolts as ina rail-joint but it will be understood that it may be adapted for otheruses and for looking a single nut or a greater or less number than thatillustrated.

It will be further noted that the device is exceedingly simple andinexpensive in con- Having thus described my invention what,

I claim is The combination with the meeting ends of two rails havingtransverse openings in their web portions, of angular fish-plates havingbase portions to restupon the base flanges of the railsand formed Withnotches in theirouter edges to receive fastening spikes, each of'saidfish-plates also having a vertical portion to engage the webs of therailsand formed with openings to register with the openings in the websof-the rails, the openings in the vertical portion of one fish-platehaving squared outer portions, the vertical portion of the otherfish-plate being formed atone end with an extension bent outwardly andprovided with an opening, and at its other end with an opening innerportion, an apertured lug having-a reduced end secured in the lastmentioned opening in said fish-plate, transverse bolts that it maybequickly and easily having a 1 flared I passed through thecaliningopenings in the fish-plates and rails and having squared portionsadjacent their heads to engage the squared portions of the openings inone of the fish-plates, nuts upon the projecting threaded ends of saidbolts and screwed against the outer face of the other fish-plate, alocking plate formed intermediate its ends with openings to receive saidnuts, one end.

of said locking plate being formed with a reduced tongue bent outwardlyand adapted to enter the opening in the extension on said fish-plate,the other end of said locking plate being formedwith an opening toreceive the apertured lug upon said fish-plate, and a split pin arrangedin the aperture in said lug to retain the locking plate in position,substantially as shown and described.

In testimony whereof I hereunto affix my signature in the presence oftwo witnesses.- ROBERTL. MANGAN. Witnesses:
